Can you explain why the ride height is so critical?

The bypass gives you a way to drive with 'different' valve settings across the entire shock length. Depending the amount of bypasses you have a more progressive one towards bump stop and a reduced rate towards full extension (nearly airborne/ deep wheeltravel). I had to use small spacers to fine tune the internal piston height to match it with the levels of bypasses. Try to find a drawing which shows the different levels of travel such a shock makes. They all work the same, external or internal. m
